Hello,

a quick question for the collective knowledge, with the most important details and information briefly summarized:

- New construction planned, building permit / planning permission application to be submitted next week
- Street: fully serviced (water, sewage, electricity, gas, etc.), road was resurfaced sometime between 1990 and 2000
- Neighbors all properly connected, but mostly older houses
- Water valve (VA) sign is located on the right side of the fence next to our driveway

I requested a pipeline map from the water utility, but they could not provide one, apparently because there are no suitable documents or maps available. The blue water valve (VA) sign indicates that a water shut-off valve is located on the main line beneath the street. The valve was found exactly where the sign indicates at the roadside (on the opposite side of the street).

During an on-site visit, the water utility representative said there should be a pipe there, but they didn’t know exactly where since it’s not marked on their maps. I was advised to carry out exploratory excavations at my property boundary, where the pipe should be located at about 1.50 meters (5 feet) depth.

The first exploratory excavation at the spot suggested by the employee (slightly to the left of the water valve sign) was unfortunately unsuccessful. I dug a hole approximately 80 cm (31 inches) wide and about 180-190 cm (71-75 inches) deep, also extending somewhat underground towards the sidewalk. I refilled the hole afterward because sand and soil were already crumbling at the edges. I plan to dig a trench to the right of this spot when time permits to continue searching for the pipe.

A detail at the boundary: The sewage maps were also somewhat inaccurate, but I did find the sewer pipe at approximately 1.20 meters (4 feet) depth, extending about 80-100 cm (31-39 inches) onto my property.

Question: What rights or options do I have if I don’t find anything with further exploratory digging? Is there any chance I can require the local water utility to perform its own search for me, ideally at no cost? I got the impression the employee was reluctant to take any initiative here. I’m happy to continue with further excavations, but each time it requires a lot of time, effort, and sweat, especially since we don’t live on-site.

Where are you planning to build: in a gap between buildings, meaning no existing structures on the lot;
and now you can’t complete the drainage plan because the location of the sewage main is unknown?
You will have to install the fresh water connection anyway.

to initiate a request for this information free of charge, if possible?
The first question is: what do you need the information for?
It could be quite simple—for example, the water supply connection might be located on the opposite side of the street.

I also wanted to say that the main pipeline is probably on the other side of the street.
And you basically shouldn’t have to worry about it. Only a company commissioned by the water utility is allowed to make the connection—they will handle it.
The actual depth is not really relevant to you either, since it’s a pressure pipeline and you don’t need to check if you can manage a slope, etc. So what is the presumed reason for the survey?

Thank you for your responses. The main line is located— as mentioned earlier— on the opposite side of the street. The appointment with the water utility representative came about because I had requested a line map. During this meeting, the representative informed me that he was not exactly sure if or where the line is located, and therefore no line map is available. As a result, I was instructed to carry out exploratory excavations at the property boundary on my own property to determine if and where the line can be found… this is considered my responsibility, and in the worst case, the utility company will dig up the street and install a new line at my expense, which was the general message.

@11ant I had located the sewer line already, which is all fine. It was mentioned only as an example because I had also conducted an exploratory excavation there due to old, inaccurate line maps. This issue concerns the water line, which, according to the valve and blue water marker, should be at our property boundary or on our property.

Oh, so there is already an existing service line to the property, and it is supposed to be reused? I’m surprised that is even possible. With our water utilities, a new line must be installed anyway for new construction. This is also due to hygiene regulations and so on.
